Google is rolling out Gemini 3 Deep Think mode to its premium subscribers today, marking a significant leap in AI reasoning capabilities. The new mode tackles complex mathematical, scientific, and logical problems that challenge even the most advanced AI models, using parallel reasoning to explore multiple solutions simultaneously.
Google just dropped its most advanced reasoning AI yet, and it's exclusively for paying customers. The tech giant rolled out Gemini 3 Deep Think mode this afternoon to Google AI Ultra subscribers, representing a major escalation in the AI reasoning wars that has OpenAI scrambling to respond.
The launch comes just hours after Microsoft teased its own reasoning improvements, showing how quickly the AI landscape shifts when breakthrough capabilities emerge. According to Google's official blog post, this isn't just another incremental update - it's a fundamental leap in how AI approaches complex problem-solving.
"This new mode delivers a meaningful improvement in reasoning capabilities, designed to tackle complex math, science and logic problems that challenge even the most advanced state-of-the-art models," wrote Tulsee Doshi, Senior Director of Product Management at Google, in today's announcement.
What makes Gemini 3 Deep Think different is its parallel reasoning approach. Instead of working through problems linearly like traditional AI models, it explores multiple hypotheses simultaneously - essentially thinking through several solution paths at once before converging on the best answer. This mirrors how human experts approach complex problems, considering various angles before reaching conclusions.
The performance numbers back up Google's bold claims. Gemini 3 Deep Think excels on notoriously difficult benchmarks like Humanity's Last Exam and ARC-AGI-2, tests specifically designed to challenge AI reasoning at the highest levels. These aren't typical AI benchmarks - they're the kind of problems that separate truly intelligent systems from sophisticated pattern matchers.
This builds directly on the success of Gemini 2.5 Deep Think variants, which recently made headlines by achieving gold medal standards at both the International Mathematical Olympiad and the International Collegiate Programming Contest World Finals. Those victories weren't just PR wins - they demonstrated that AI had crossed a threshold in mathematical reasoning that many experts thought was years away.
